Overview
Anorectal agenesis refers to congenital absence or malformation of the anus and rectum, often associated with complex congenital anomalies. 1Diagnosis
Clinical assessment identifying absence or imperforate anus.
Imaging studies (e.g., ultrasound, MRI) to evaluate associated anomalies like hydronephrosis or malformations of adjacent structures. 1
Genetic testing may be considered in cases with suspected mosaicism or syndromes like PHACES. 1Management
Surgical intervention is essential, typically involving colostomy initially followed by definitive repair (e.g., abdominoperineal pull-through).
Postoperative care includes management of stoma and monitoring for complications such as bowel function issues.
Sedation may be required for minor procedures, using propofol cautiously to balance comfort and recovery time. 2Special Populations
Pediatrics: Early surgical intervention is critical to prevent long-term complications and ensure proper bowel function development. 1
Comorbidities: Patients with associated conditions like hydronephrosis require multidisciplinary management involving urology. 1Key Recommendations
Perform comprehensive imaging to identify associated congenital anomalies in patients with anorectal agenesis. (Evidence: Moderate 1)
Initiate surgical correction early in pediatric patients to optimize outcomes and minimize complications. (Evidence: Expert opinion 1)
Consider patient comfort with judicious use of sedation in minor procedures, balancing recovery times. (Evidence: Weak 2)References
